Display panel, display device and manufacturing method thereof

Abstract

An embodiment of the present disclosure is directed to a display panel, a display device, and a manufacturing method thereof. The display panel includes an array substrate, an anode layer positioned on the array substrate, and a light-emitting layer. The anode layer includes a reflective layer and a first electrode layer positioned sequentially along a direction away from the array substrate. The reflector layer has reflective surfaces on one side of the reflector layer facing away from the array substrate. Two adjacent reflective surfaces are intersected. When the light emitted by the light-emitting layer passes through the first electrode layer and reaches the reflective layer, it can be reflected at different reflection angles after being reflected, thereby increasing the luminous angle of the light-emitting layer and improving the luminous viewing angle of the display panel.
